"As of right now, it could be either one or it could be no one," Hudson said when asked if there could still be charges filed from the incident. "It depends what that iPad has on it, what that footage shows."

Shortly before 3 p.m. Monday, Shellie Zimmerman called 911 and told the dispatcher that George had shown up to her father's home and that an altercation soon followed. She said he punched her father. She also said George was threatening them with his gun.

"He's in his car, and he continually has his hand on his gun and keeps saying, 'Step closer,'" Shellie told the dispatcher. "He's just threatening all of us.

"I don't know what he's capable of," she added. "I'm really scared."

Police say George told them Shellie and her father were the aggressors in the altercation.

Zimmerman's attorney, Mark O'Mara, told reporters that his client was the only one who lived in the home and that, even though the house is under his in-law's name, he and Shellie were the only ones living there.

Shellie recently filed for divorce from George. She also claims that she and George had a big fight on the night he shot and killed Trayvon Martin.

O'Mara told reporters on Monday that George did have his gun during his altercation with Shellie but that it was holstered under his shirt and that he never took it out.
